> Closing of SSE connection by client is not detected and handled on the server part.
> This results in server leaking resources when it is the clients responsibility for deciding on the lifetime of SSE connection.
> My particular scenario is:
> Status notifications for devices manged by the server are sent to the client (browser), this is a continues stream. That stream lives until browser tab/window is closed, which results in client closing the underlying SSE connection.
> SseSinkImpl is not informed of connection being closed. 
> At the same time the exception set in  org.apache.cxf.jaxrs.sse.SseEventSinkImpl#dequeue {code}future.completeExceptionally(ex);{code} in case of channel being closed is not acted upon internally within SseSinkImpl.
